[newbie] Mouse Driver screwup in KDE

[Ken]

Hello all, first off, im totally new to Linux and everything about it.
Anyways, I installed Linux Mandrake last night, all went well, but when
it boots now, and loads KDE, my mouse wont work, it just goes to the
upper right hand side corner and wont come out. I have a Genius
Netscroll (PS/2) Mouse. I chose those drivers durning setup. How do i go
about changing the mouse driver, when i cant use the mouse in KDE. Any
help is appreciated!

Thank you.

Ken
